§DETECTOR §STATIC

STG-63 Series

AC TACHOGENERATOR REVOLUTION SPEED DETECTORCOMMON SPECIFICATION■ USEThis product receives output voltage signal oroutput frequency signal of AC tachogenerator anddetects starting operation signal, control signal, overspeed stop signal and outputs contact signal. As thisproduct is all electronized, detection with highsensitivity, high speed is possible. No influence ofvarious factors such as external noise.

■ FEATURES► High quality, high reliability and noise
resistance design.
► 3-step detection level equipped.
► Easy setting adjust from exterior byscrewdriver adjustor.
